Abstract (en)
In this road surface displacement detection device, for each frame of an image obtained by a stereo camera that images a road surface in a movement direction of an object such as a vehicle, for example, an arithmetic processing circuit detects heights of the road surface at a plurality of points for detection at different distances from the stereo camera, and superimposes information about the heights at the plurality of points for detection, which are detected for a plurality of frames, on each other while considering a movement distance of the object between the plurality of frames.
